Why it's free to use

  • Filed December 10, 1999. A US utility patent lasts 20 years from filing, so its term ended December 10, 2019.
  • Patents filed before May 29, 2000 can't get a term adjustment for USPTO delays, and any other extension is capped at five years, so it can't still be in force.
  • We haven't checked its US family, and a later related patent could still be in force. We check US rights only.
